BACKGROUND

1. Field of the Invention

Present embodiments generally relate to a power cord for medical equipment which is movable to and from various locations. More specifically, present embodiments are related to power cords with integral location tracking hardware installed on or in the cord allowing instantaneous location information for any device the cord is connected to.

2. Description of the Related Art

The United States Food and Drug Administration (FDA) requires manufacturers or users to track certain medical devices which are utilized in the medical field in order to ensure that they may be promptly located once into commercial distribution. This may facilitate notifications and recalls of medical equipment ordered by the FDA which otherwise may cause serious risk to health if not located promptly. Manufacturers must adopt a method of tracking devices where failure would be reasonably likely to have serious, adverse health consequences or if the device is a life-sustaining or life-supporting device used outside of a device-user facility.

For example, the FDA has issued orders to manufacturers on devices which function as breathing frequency monitors, continuous ventilators, DC-defibrillators and paddles and ventricular bypass (assist) devices. Tracking augments the FDA's authority to order mandatory recalls and require notification of health professionals and patients regarding unreasonable risk of substantial harm associated with a device. Title 21 of the Code of Federal Regulations (CFR) provides further information on tracking requirements which are set forth by the United States Federal Government.

The current method of scanning equipment for purposes of locating or tracking involves scanning of a piece of equipment then subsequently moving the equipment to a location where it is intended to be used. However, in some circumstances, equipment may be moved without being scanned so that it ends up in an alternate location than recorded by the scanning process. Further, it is also somewhat time-consuming to require manual scanning of each piece of equipment each time the equipment scans into a storage area or scans out for movement to a location for use.

Further, once scanned, the hospital or health care provider staff, for example, may be required to go to a separate database to look up the location where the equipment is supposed to be located although such listing or recordation may not be accurate. Accordingly, there is a need to overcome these and other deficiencies while meeting at least the desired goals described above, including, but not limited to, improved scanning of equipment and ability to locate the equipment.

The information included in this Background section of the specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and is not to be regarded subject matter by which the scope of the invention is to be bound.

DETAILED DESCRIPTION

It is to be understood that the location power cord and related system for use is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The embodiments are capable of other embodiments and of being practiced or of being carried out in various ways. For example, one embodiment is capable of being combined with a second embodiment to create a further embodiment. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected,” “coupled,” and “mounted,” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. In addition, the terms “connected” and “coupled” and variations thereof are not restricted to physical or mechanical connections or couplings.

Referring now in detail to the drawings, wherein like numerals indicate like elements throughout several views, there are shown in FIGS. 1-8, various embodiments of a location power cord, system and method for use thereof. The location power cord includes a power cord including a sheath having a plurality of conductors extending therethrough between a first end where a first plug is located and a second end where a second plug is located. Located along the power cord sheath is a location module housing wherein a battery and location module are located. Additionally, a power supply and communication module may be located therein as well. The location power cord may be connected to a medical device and a power source and may determine its location using various techniques. By way of the communication module, the location power cord may then communicate to a location server so that when accessed, the location server can provide real time information and location of the medical device to which the location power cord is connected.

Referring now to FIG. 1, an exemplary location power cord 10 is shown in perspective view. The location power cord 10 includes a power cord 12 and a location module housing 14 located between ends of the power cord 12.

The power cord 12 includes a cord sheath 16 through which a plurality of conductors 46, 47, 48 (FIG. 2) extend. The cord sheath 16 may be formed of, for non-limiting example, a flexible plastic material which forms a sheath over the conductors. The power cord 12 includes a first end 18 and a second end 20. At the first end 18 of the power cord 12 is a first plug 22. The first plug 22 of the exemplary embodiment is a male plug having a plurality of blades 24 and a ground plug 26. At a second end 20 of the power cord 12 is a second plug 30. In the depicted embodiment, the second plug 30 is a female plug having three blade apertures 32. The first plug 22 and second plug 30 may be either male or female. The first plug 22 may be connected to a power source such as a 120V AC source which is standard in homes and commercial complexes. The second plug 30 may be connected to a medical device (not shown) which is required to be tracked according to FDA guidelines set forth in the Code of Federal Regulations. The plugs 22, 30 may be molded on plug attachments of the non-locking type configuration. These may be rated, for example, at 15 or 10 amps and 125 or 250V usage. The plugs 22, 30 may be of the straight type as depicted, that the longitudinal axis of the flexible cord is parallel to that of the line blades, or may be of the right angle or left angle type wherein the longitudinal axis of the flexible cord 12 is at a right angle to that of the line blades and blade apertures 24, 32 and again may be molded to the power cord sheath 16. These requirements are set forth in the UL Standards, Section 817 described as “hospital grade”.

Referring now to FIG. 2, the location module housing 14 is shown in a perspective view with a portion of the location module housing 14 cut away to reveal interior components of the assembly of components located therein. In the depicted embodiment, the power cord 12 is in electrical communication with the location module housing 14 and conductors within the cord sheath 16 extend into the module housing 14 and are in electrical communication with the various components located therein.

The depicted embodiment includes the housing cover 40 and a base 42 which form a hollow compartment 44 wherein various components are located. Within the compartment 44 are a printed circuit board 50, a transformer 52 and a battery 54. One or more of these components may or may not be present in other embodiments. For example, in some embodiments, no battery is present, and power is obtained exclusively from the plurality of conductors 46, 47, 48.

The printed circuit board 50 provides communication with a cellular phone system and/or one or more satellites in order to provide location information to the system within which the location power cord 10 is utilized. Therefore, the printed circuit board 50 defines, at least in part, a location communication module as well as a mobile or cellular communication module. The transformer 52 receives power from conductors 46, 47, 48. The transformer 52 converts the higher voltage AC electricity to a lower voltage DC electricity suitable for use in charging the battery 54 and powering the printed circuit board 50.

Referring now to FIG. 3, the housing cover 40 is exploded from the base 42 and the various components are exploded apart as well. The conductors 46, 47, 48 (FIG. 2) are not shown simply for sake of clarity. However, one skilled in the art should understand that the conductors utilized within the power cord 12 provide power to the transformer 52 which powers the battery charging and the printed circuit board 50.

The housing 40 and base 42 may be formed of a thermo-formed plastic or other molded material such that the housing cover 40 may be adhered to or fastened to the base 42. The housing 40 and cord sheath 16 may also be formed of like materials to aid in joining the two parts, or may be of different materials.

Disposed above the base 42 is a transformer 52 which is connected to the conductors 46, 47, 48 (FIG. 2). The transformer 52 is supplied with either 120V or 240V AC electricity, for example at 50 or 60 hz input. The transformer 52 converts the higher voltage AC input to a lower voltage DC output. For example, the output voltage may range from 1.5V to 12V and according to one embodiment may be 5V DC which is suitable for charging the battery 54 and operating the circuitry on the printed circuit board 50.

Above the transformer 52 is a battery 54. The battery 54 may be a lithium ion battery which is rechargeable by way of connection and power supplied from the transformer 52. The battery 54 may be directly connected to the printed circuit board 50 or alternatively, may be directly connected to the transformer 52. The lithium ion battery is desirable for its ability to recharge multiple occasions without developing battery memory and reducing life and capacity of the battery. However, the battery 54 does not necessarily have to be lithium ion as other types may be used, for example nickel cadmium batteries are also rechargeable and may be utilized. The exemplary battery 54 may be a 1,100 milliamp hour battery or a 4.7 watt-hour battery. Additionally, a larger battery may be utilized if desirable for longer operational time when the soul power source is the battery 54.

Above the battery 54 is the printed circuit board 50. The printed circuit board 50 provides various functions for the location power cord 10. First, the printed circuit board 50 provides communication with one or more components that may be used to obtain a location of power cord 10, so that the printed circuit board 50 may locate the location power cord 10 to a specific location, e.g., on Earth and/or relative to some known location. These location-obtaining components may form part of indoor or outdoor position systems, and may include but are not limited to one or more GPS satellites, one or more cellular towers (e.g., using triangulation), one or more Wi-Fi access points (also referred to as Wi-Fi-based positioning system, or “WPS”), Internet Protocol positioning system components, magnetic positioning components, and so forth. Additionally or alternatively, in some embodiments, one or more inertial measurement components contained within location module housing 14 may be used to determine location.

Additionally, the printed circuit board 50 may also provide cellular communication with a cellular data service 300 (FIG. 6) so that locational information may be transmitted to one or more servers 200 (FIG. 6) by way of the internet 400 (FIG. 5). This server 200 allows for data base registry of the location of the location power cord 10. In order to accomplish this cellular data service 300 connection, the printed circuit board 50 may include a SIM card receptacle. Additionally, the printed circuit board 50 may include a reset button which may temporarily de-power the operating system and cause the on-board programming to reboot. Further, a USB port or other micro-USB port may be utilized to program a central processor on the printed circuit board 50. The processor may provide for the location communication functionality and the cellular/data communication functionality. The location communication may be programmed to perform at various intervals. When the interval is set to a higher rate, the battery 54 may die sooner while oppositely, if the interval is set at a lower rate, the battery 54 may last longer. According to some embodiments, the interval for location communication may be set from between about once every second to about once every hour.

The printed circuit board 50 may also comprise one or more antennas for use in receiving various signals, such as a GPS signal from one or more GPS satellites orbiting the earth, the cellular data communication to send the location to a server and to additionally receive data from cellular antennas which may be used additionally to triangulate for purpose of locating the location power cord 10.

Referring additionally now to FIG. 4, a schematic depiction of the wiring for power is depicted. The conductors 46, 47, 48 which are located within the power cord 12 are shown extending through the compartment 44 of the housing cover 40 and base 42 (FIG. 2). The conductors 46, 47, 48 may represent positive, negative and ground connections for example. The conductors 46, 47, 48 are connected to the transformer 52 by transformer leads 56, 57, 58 in order to provide input power to the transformer 52. As previously discussed, the transformer 52 converts the 120V AC input to a 5V DC output. The transformer 52 is in electrical communication with the printed circuit board 50 as indicated by arrow 53. The circuit board 50 is also in electrical communication with battery 54 to provide a communication channel between the transformer 52 and the battery 54. In the depicted embodiment, the circuit board 50 includes two arrows 55, 59 extending between the circuit board 50 and the battery 54. These connections provide power to the battery 54 for charging and power from the battery to the board 50 for powering the location power cord 10 when the location power cord 10 is not connected to a power source. Additionally, a broken line 51 is depicted and represents an alternative embodiment wherein the transformer 52 is directly connected to the battery 54 for charging purpose. This might be, for example, used in combination with the connection 59 between the battery 54 and circuit board 50.

Referring now to FIG. 5, a schematic view of the printed circuit board 50 is shown. The printed circuit board 50 comprises a location communication module 60 which may comprise the one or more antennas for communicating with, e.g., various GPS satellites, cellular towers, Wi-Fi access points, and so forth.

The printed circuit board 50 further comprises a mobile/cellular communication module 62. The module 62 may comprise 3G, 4G, LTE, CDMA, GSM, TDMA and satellite communication means. This list is not exhaustive however, and other forms of cellular/mobile communication may be utilized.

Further, a power module 64 may be utilized to direct power from the transmitter 52 or from the battery 54 to the module 60 and the mobile/cellular communication module 62.

Referring now to FIG. 6, an example system is depicted for use with the location power cord 10, in accordance with some embodiments. The printed circuit board 50 (FIG. 3) includes two forms of communication. In one form, the location power cord 10 receives a signal from one or more GPS satellites 100. In a second form of communication, the location power cord 10 communicates with a mobile phone network 300. With regard to the first form of communication, the higher the number of satellite signals received by the location power cord 10, the greater the level of accuracy of at least one locating feature for the location power cord 10. The system further comprises a mobile phone network 300, the location server 200, an internet connection or access 400 for communication and a location 500 where the location server 200 may be accessed from, for example a hospital 500. While a single server 200 is shown in the exemplary embodiment, it should be clear that the server 200 may be two or more servers wherein at least one of the two servers is a back up server. Additionally, the at least one server 200 may be a cloud based server.

In embodiments that employ GPS technology, the GPS technology may work to use radio signals sent by satellites 100 in space. The satellites 100 orbit the earth in cyclical patterns and at any given time, a plurality of satellite signals (e.g., four or more) may be accessible to any point on the surface of the earth. When a receiver device, such as the location power cord 10, is activated, radio waves are sent out and the satellite 100 may track the device. The location power cord's 10 exact location is determined through a process called triangulation or an alternate version called trilateration where three satellites work together to narrow down possible location points while a fourth satellite compiles data and decides on a match. Distance calculations are made based on how long it takes the radio signals to travel back and forth between the receiver of the location power cord 10 and the satellite 100. In order for GPS to work properly, there should be a clear line of sight between the receiver on the printed circuit board 50 and the sky. As this may not be the case, assisted GPS improves upon the standard GPS technology to utilize a cellular network's assistance server which is connected to a reference network. Through the use of cell towers, the location power cord 10 relays satellite information to a server 200 by way of internet 400. In the depicted embodiment, the cellular network tower 300 is shown in communication with the internet 400. The cellular tower 300 receives GPS information received from the GPS satellites 100 at the location power cord 10 and transmits the data to the server 200 by way of internet 400. The assisted GPS technology allows the cellular network server 200 to receive the data and process incoming data at a higher rate than GPS receivers so information is transmitted faster and is typically more accurate than what a GPS receiver can relay on its own.

A hospital 500 is shown in the embodiment as well. The exemplary hospital 500 may communicate by way of the internet to access information at the location server 200 and quickly acquire database information on the location power cord 10. Thus, the location of the location power cord 10 and associated device may be found quickly by way of, for example, a web-based application.

In this embodiment, the location power cord 10 may further have model and serial number of an associated piece of equipment programmed into the printed circuit board 50, for example on firmware or on a memory chip associated with the printed circuit board 50. This will be added to a user account, for example, an owner of a device or manufacturer and all data from the associated location power cord 10 will be captured and logged into the tracking software which is either located on the user's computer, for example at the hospital 500 or alternatively, on the location server 200. Thus, when a user logs into the software or application, the user can access in real-time location of the location power cord 10 and the associated medical device from the server 200. Further, it may be that when a user at a hospital or other facility logs into the tracking software, all devices associated with this user may be seen so that a specific medical device may then be selected from the group of devices for further locational information. Still further, the at least one user or an alternative person at a different location may further be able to utilize a mast log-in account to modify information related to any medical device and any location power cord 10.

Referring now to FIG. 7, a method of use of the location power cord 10 is described. First, the location power cord is connected to a medical device 72 and powered up from a power source or battery 54. Next, the location module receives a satellite signal at step 74. The printed circuit board 50 may determine location or coordinates which are subsequently sent to a server at step 76. Finally, the server may be accessed via the internet in order to determine the location of the location power cord 10 and associated medical device 72 at step 78. Further, the user who logs in to check the location of a medical device and associated location power cord 10 may further be able to run history reports to show locations where the location power cord and medical device have been through some preselected historical time period, in addition to the real time location. The tracking software may additionally have geo-fence capability for which alarm conditions may be enabled to provide an alarm if a location power cord 10 and corresponding medical device are moved to a location other than where the location power cord 10 is supposed to be. Still further alternative alarms may be utilized and enabled, for example but not limited to, low battery condition of the power cord 10. Still further, emails or SMS messages may be sent from the server 200 to notify a responsible person that alarm conditions have been triggered, for example. These may alarms and email/messaging services may be selectively set for different conditions and whether or not to send since notifications of alarm conditions may be suitable in some situations but not others.

Referring now to FIG. 8, an exemplary screen shot of a tracking software or application is depicted as seen by a user logging into the location server 200 (FIG. 5). In the exemplary embodiment, the tracking software may utilize a mapping application 402 on the internet 400, for example GOOGLE maps to display a location of the power cord 10 and associated medical device. The GPS location server 200 may provide a determined geo-positional signal to either the mapping application 402 which may be an internet based application or an application installed on a locale computer where the lookup for the medical device is occurring.

Once the application 402 is started, identifying information for the power cord 10 may be provided by a serial number for either the cord or the medical device. Further, the mapping application 402 may convert the geo-positional signal to a locational image on the application 402. In the depicted embodiment, at least one geo-positional signal is in a standard as devices 404, 406. The standard depicts serial numbers corresponding to devices 404, 406. Additionally, the mapping application 402 depicts markers 408, 410. Thus a user at the local computer, for example at a hospital or medical device sales/rental facility may use the standard information 404, 406 to correspond to markers 408, 410 and determine a location of a medical device and power cord 10 and any associated alarm conditions.

While several inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the invent of embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms. The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases.

Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.

In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.

The foregoing description of several methods and an embodiment of the invention has been presented for purposes of illustration. It is not intended to be exhaustive or to limit the invention to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention and all equivalents be defined by the claims appended hereto.
